Title: Method and apparatus for coding audio signals based on perceptual model
Inventor: JOHNSTON JAMES DAVIS
IPC: G10L21/003
Filed: 1993-02-23
Granted: 1999-05-18
Abstract: Coding of high quality stereophonic audio signals is accomplished in a perceptual filterbank coder which exploits the interchannel redundancies and psychoacoustic. Using perceptual principles, switching between a normal and short window of input samples improve output signal quality for certain input signals,particularly those having a rapid attack. Switching is also accomplished betweencoding of left and right channels and so- called sum and difference channels in response to particular signal conditions. A number of new perceptually based techniques, including improved threshold determinations, result in high quality.

Patent CA-2106798-C (CA)
Inventor: ALLARD RANDALL NOEL
IPC: A61B17/70
Filed: 1993-09-23
Granted: 2004-05-11
Abstract: The telescoping rod to rod coupler of this invention substantially eliminates the chances of the two rod sections disconnecting from one another by providing a relief in the male section to define a hook shaped end. The hook shaped end in association with a clamping screw carried by the female section requires the rod sections to axial rotate 180 degrees in a screw-like manner during assembly and disassembly. The clamping screw constitutes an abutment or stop for engagement with the hook shaped end to provide a positive stop to prevent the sections from accidentally sliding past their extremes and out of engagement with one another during the surgery.      Further, the reliefs provided within the male telescoping section, permit the two rod sections to be firmly affixed to one another with one section axially rotated slightly relative to the other rod section.

Granted: 1999-06-01
Abstract: A user interface technique oparates in the environment of a processor-controlled machine for executing a program that operates on a set of underlying data and displays a visible representation thereof.   The system generates a visual depiction of a movable sheet having a number of delineated regions (active areas), responds to a first set of signals for positioning the sheet relative to the visible representation, responds to a second set of signals characterized by position information (typically cursor position) relative to the sheet and the visible representation, and generates a third set of signals to the program.   The third set of signals depends on the relative position of the sheet and the visible representation and on the position information that characterizes the second set of input signals.   The delineated regions may be thought of and referred to as click-through tools.

Abstract: A rekeyable cylinder and its keys include a  core and  a  plug. A plurality  of  pin  cell  is  formed respectively in the core and plug and is perpendicular to the axis of keyway in the plug.   Each pair of pin cells  have  a  spring,  an upper pin  and  a  lower pin disposed therein.  In locking status, upper pin is moved into pin cell of plug,  and lower pin is moved  into keyway,  thereby plug cannot rotate or move  in axial direction.  A first control pin is disposed at one end of the core and engages with an annular groove formed around the circumference of the plug, thus allowing the plug to rotate but  cannot make  linear movement.   A control key can release the first control pin from the annular groove thus allowing plug be pulled out of the core.   The lower pin in the plug can be changed and adjusted to match a new key cut profile of a new change key.   Thus a change key can be replaced without to replace the cylinder.

Granted: 1998-09-22
Abstract: A plug flow process for the production of chlorine dioxide by reacting  chloric acid and/or  an alkali metal  chlorate, optionally a mineral acid and a reducing agent in such propor-tions that chlorine dioxide is produced.  Reactants are continu-ously fed to a plug flow reactor under conditions that chloride dioxide is produced as the reactants flow through the reactor.          The process stream has an acidity between 2N and 11N.   The process stream is subjected to superatmospheric pressure in the reactor sufficient to maintain the formed chlorine dioxide in solution.  After removal of the chlorine dioxide from the process stream exiting the plug flow reactor, the process stream can optionally be fed to a second chlorine dioxide generator for further reaction.

Abstract: A torque-resistant hydraulically settable packer is coaxially positionable within a subterranean well flow conductor and has a tubular body that carries a circumferentially spaced series of radially outwardly movable slip anchors having, on outer side surfaces thereof, gripping teeth with lengths that are sloped relative to the longitudinal axis of the tubular and to a plane perpendicular. Inner side surfaces of the slip anchors are engaged by circumferentially spaced flat outer side surface areas formed on the facing frustroconical ends of an opposed pair of annular setting wedge members coaxially carried by the tubular body and being axially drivable to radially outwardly shift the slip anchors to their setting positions. As the slip anchors are being set, an annular resilient seal structure is simultaneously compressed in an axial direction against a setting force limiting member telescopingly received in one of the setting wedge members, and radially deformed outwardly into sealing engagement with the interior side surface of the well flow conductor. After the slip anchors are set, the seal structure is further compressed in an axial direction by hydraulically shifting the tubular body relative to the slip anchors. If this subsequent axial compression force exerted on the seal structure is above a predetermined maximum level the setting force member is wedgingly driven into its associated setting wedge member to limit the total axial compression force imposed on the seal structure.
